IMPROVEMENTIN CHAIR SEATS AND BACKS.

Specification forming part of Letters Patent No. 196,824, dated November6, 1877; application filed August 18, 1877.

To all whom it may concern Be it known that I, PAUL BATH, of Jersey CityHeights, in the county of Hudson and State of New Jersey, have inventeda new and Improved Chair Seat and Back, of which the following is aspecification:

In the accompanying drawings, Figure 1 represents a verticallongitudinal section of my improved chair seat and back, and Fig. 2 atop view of the detached spring-section of the same.

Similar letters of reference indicate corresponding parts.

The object of this invention is to improve the chair seat and back forwhich Letters Patent were granted to me March 13, 1877, No. 188,410, sothat a superior finish and still more increased elasticity are impartedto the seat or back, and an exact, but ready-made, imitation of thepresent upholstered seats and backs is furnished for the trade, forminga separate article of manufacture.

The invention consists of a molded pasteboard seat or back, havingcentral hole, stuffing, and covering, in connection with a separatepasteboard section bolted thereto, and carrying auxiliary springs, toincrease the clasticity of the stufling.

It consists, further, of the pasteboard seat having a circumferentialmolding and a similar stuffed edging attached thereto.

In the drawing, A represents the pasteboard bottom of my improved seator back, which is stamped up by suitable machinery with a central round,square, or oval opening, a, and a concaved molding, b, of suitabledepth, extending around the opening. The sides of the pasteboard bottomare turned down to form flanges d, by which the seat or back may beattached to the chair or other frame. The pasteboard bottom A is coveredat both sides with canvas or other fabric B, that passes across thecenter hole a, so as to close the same. The fabric B is made convex andflexible above the hole, and isacted upon by a number of spiralauxiliary springs, G, that are secured to a second pasteboard section,D, of less width than the main section A. The pasteboard section D ismade concave, with an outwardlyextending circumferential flange, D, bywhich the section D is firmly bolted or otherwise seboard covering B,and returned, not only by its own inherent elasticity, but also by theauxiliary springs, to its original position, without ever settling orcaving in by use. The

pasteboard A is also stamped with a circumferential concave molding, e,for the purpose of receiving a stuffed edging, E, of circular shape,that is glued or otherwise attached to the molding e, so as to extendaround the entire seat, and serve for the binding off of the edge of thesame, in imitation of the edge of the usual leather seats and backs.

The seats and backs thus constructed may be directly applied tothe-chair and other frames. They furnish comfortable supports for thebody, and assume instantly their natural convex shape after the pressurethereon is relaxed. Thus a new article of manufacture for manufacturersof furniture and others is provided, which may be directly applied, incheap and convenient manner, to new or old furniture, withoutrequiring-the repairing of the same by an upholsterer.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. The pasteboard bottom A, having acentral opening and a canvas covering, B, for the latter, in combinationwith a detachable auxiliary spring-section attached to the under side ofsaid bottom, substantially as and for the purpose set forth.

2. The combination of the flanged and concaved pasteboard section D andspiral springs O with the pasteboard bottom A, having a central opening,and a canvas covering, B, for the latter, substantially as and for thepurpose set forth.
